Based on pseudo-people flow, this study quantitatively clarifies the spatial distribution of stranded individuals at the time of disaster occurrence and the occupancy and sufficiency rates of various facilities after a certain period across multiple scenarios. The analysis reveals that integrating evacuees into temporary facilities and designated shelters without distinction can reduce the occupancy rate by more than 100% compared with implementing separate management. Furthermore, estimating the necessary amount of stockpiled supplies requires a comprehensive approach that considers not only the characteristics of supplies but also the facility locations and time of disaster occurrence.
